Item Open Access Examining Local Policy Responses to Changing Hazards in Coastal North Carolina(2020-04) Bollt, Keith; Fogarty, Darren; Mullins, SuzanneAs climate change increasingly threatens global coastlines, it is key to understand how policymakers are responding on a community scale. Existing research, however, has failed to systematically describe local policy responses to changing hazards. Focusing on three representative North Carolina counties— Carteret, Dare, and New Hanover—our Master’s Project seeks to address this gap in the literature. We have compiled a comprehensive index of coastline adaptation, land use planning/zoning, and septic system management policies for the towns and counties of the study area. Our project demonstrates that policy responses vary widely, with some localities doing far more than others to prepare for climate-induced coastal change. We also perform a brief case study of a particular town, Nags Head, that stands out as best positioned to adapt to such shifts, and speculate on how other “laggard” towns may emulate the strategies deployed by Nags Head and policy “leader” communities.Item Open Access Forecasting the value of recyclable waste streams for a circular economy transition in Orlando, Florida(2018-04) Kanaoka, KoichiThe circular economy is a paradigm that views waste as a valuable resource, creating value for local economies through waste recycling and reuse. Despite the benefits of waste recovery, the national recycling rate has remained stagnant around 34% for the past decade in the U.S. This Master’s Project for Duke University’s Nicholas School of the Environment aimed to quantify the economic potential of improving recycling rates in the Orlando Metropolitan Statistical Area (MSA) through: (1) forecasting the value of recyclable municipal solid waste generated in Orlando MSA, and; (2) conducting a benefit-cost analysis (BCA) of building a material recovery facility (MRF) in Orlando. Forecasts and BCA were conducted by incorporating uncertainties from commodity price volatility. Results from the study suggested that values of single-stream recycling waste in Orlando MSA may reach $100 million in 2027, from $72 million in 2015. Cardboard and aluminum cans accounted for 70-90% of the waste stream’s value, while only accounting for 32% of the weight. The BCA revealed that building a MRF in Orlando MSA is expected to be profitable for the municipality. The cost for building the MRF was expected to be recovered as early as in the fourth year. Sensitivity analysis showed that an initial processing cost of $85 per ton, a $10 increase from the base model’s $75 per ton, made building a MRF expected to be unprofitable. The results from this study may not apply to other municipalities, since Orlando MSA already had a functioning collection infrastructure for recyclables. The study also raised questions regarding the optimal design of recycling programs.Item Open Access How can a city enhance delivery of co-benefits from a green infrastructure program?(2019-03-17) De Luise, AlsionThis MP explores how cities can enhance delivery of co-benefits from green infrastructure investments designed and implemented to deliver specific water-related outcomes. Inter-linked methodological approaches used included review of scholarly literature with thematic analysis; case study analysis of the City of Philadelphia’s Green City, Clean Water program; and semi-structured informant interviewing. The MP concludes that issues including an absence of co-benefit indicators in the M&E framework, collaboration-related transaction costs from siloed government processes, and the water-focused ambition of the legal contract with the EPA have meant that the water investment has not yet been sufficiently leveraged to maximize co-benefit outcomes. Nevertheless, building off existing good practices identified, a number of very actionable ways that cities can enhance delivery of co-benefits are presented for consideration by municipal managers.Item Open Access Innovative Financing for Green Stormwater Infrastructure: Lessons Learned from Energy Efficiency(2016-04-29) Starkman, KendallStormwater management can be a significant challenge in urban areas. As population density grows and impervious surface cover increases, the amount and intensity of stormwater runoff escalates correspondingly, placing added stress on water management systems and natural ecosystems. Green stormwater infrastructure (GSI) is increasingly being seen as a critical tool for addressing these challenges (Garrison and Hobbs 2011). Although a number of cities across the country have turned to GSI as a key component of their stormwater management system, oftentimes the scope is limited to public property. Since GSI is a distributed approach to stormwater management, programs must engage private property owners (Francis 2010). Energy efficiency programs have seen significant success engaging private property owners across the built environment despite experiencing many of the same challenges attracting investment in the face of high up-front costs and limited inherent collateral value (Palmer, Walls and Gerarden 2012). This project aims to better explain the key factors that influence the success of three types of energy efficiency financing programs in the United States and draw cross-sector parallels to GSI in order to inform a decision-making framework for GSI program design. This is accomplished through 1) a review of the existing literature on energy efficiency program design and the potential equivalencies between energy efficiency and green stormwater infrastructure, 2) an exploration of three financing mechanism case studies, and 3) the definition of decision criteria to provide initial direction for the evaluation of appropriate financing mechanisms in a specific case. In order to better understand the settings in which specific energy efficiency financing mechanisms would be most appropriate, this research evaluated three financing mechanisms: on-bill repayment, PACE financing, and performance contracting with Energy Services Companies (ESCOs). The data informing these case studies was gathered through research of secondary sources, a series of interviews of energy efficiency program administrators and energy and/or GSI industry experts, and a review of example programs. The case analysis informed a consideration of how each financing mechanism could be applied in the stormwater context. The findings reach beyond the existing literature to examine national level themes and provide a local-level decision making framework. Based on the findings of this report, a number of key factors exist that can direct decision-making around green stormwater infrastructure financing. First, a fundamental consideration is whether a stormwater fee structure exists to create the opportunity for savings. Assuming this requirement is met, the following criteria indicate the suitability of the three financing mechanisms for a specific jurisdiction: building stock of greatest concern, authorizing legislation, political buy-in, incentives, and regulatory requirements. The importance of each criteria varies for each financing mechanism. PACE programs are most appropriate in states with a history of PACE authorizing legislation, strong regulatory drivers for action and a wider range of target property sizes. Performance contracting is more appropriate in places with a high concentration of large-scale commercial building stock, limited legislative support and multiple available incentives. On-bill repayment programs are most applicable where there are more opportunities to pursue small-scale GSI and strong regulatory drivers for action. In addition, shared key factors that apply to all three of the case financing mechanisms will impact program viability and are important to consider in program design. These include the stormwater fee size and available margin, the potential to offer credit enhancements, the ability to leverage an economy of scale, the policy requirements affecting loan term stringency, and existing availability of financial partners. An applied analysis of how these findings impact Seattle, WA further illustrates the implications of these findings. The City has an itemized stormwater fee structure, an existing stormwater consent order and is actively investing in GSI. PACE financing is not possible in the state due to legislative restrictions. However, a stormwater credit already exists in the city and a commercial GSI program would target medium to large-scale commercial customers. Therefore, it is recommended that the City of Seattle explore performance contracting by supporting the development of a GISC. In order to make this possible, the City could create a public private partnership with local innovators and consider opportunities to provide credit enhancements. Secondarily, the City might also consider the potential to offer on-bill repayment for small scale projects. In both cases, the City will need to conduct further inquiry into the financial implications and political feasibility of these endeavors and create a framework for measurement and verification of stormwater savings.Item Open Access Mapping Rio Grande Water Rights: A Decision Support Tool for Ecosystem Restoration(2018-04-27) Murray, MeganThe Nature Conservancy of Texas (TNC-Texas) and TNC (TNC-Global) are pursing efforts to identify and acquire water rights that could be dedicated or in other ways managed for the benefit and protection of environmental flows. Due to recent alliances and funding streams, TNC is particularly interested in water rights in the Lower Pecos and Upper Rio Grande watersheds, sub-watersheds of the Rio Grande in Far West Texas. Before any transactions are made, The Nature Conservancy must determine which water rights they are interested in acquiring. TNC has been working on a water rights mapping platform that allows them to assess how much water is left in the river after the initial diversion, where the return flows go, and if purchased water will reach TNC’s designated priority streams. However, this analysis is limited when water rights are not in the correct location. Thus, this project remedied these inaccuracies in the Lower Pecos and Upper Rio Grande by moving the water right to the correct location. The resulting products are a static map and web application version that contain the water rights along with other important features like watershed boundaries, water monitoring stations, priority stream segments, and endangered species’ ranges. With water rights in the correct location, it is possible to characterize how water is used in the region and by whom. This report highlights the major water users in each watershed and explains their operations in detail. In addition to who, what, and where of water use, the report emphasizes some of the key legal and third-party considerations TNC should evaluate. The The Nature Conservancy intends to use the map and supporting documentation as a decision support tool for their ecosystem restoration projects.Item Open Access Methods Federal Government Agencies Implement to Comply with the National Environmental Policy Act(2016-04-27) Carter, Lee Ellen; Carter, LeeThe National Environmental Policy Act (NEPA) became the first major environmental law in the United States (US) in 1970. NEPA requires federal agencies to determine significant environmental impacts of their actions to the fullest extent possible. Each agency is given flexibility in their compliance (Congress, 1970). Oversight of agency compliance with NEPA was given to the Council on Environmental Quality (CEQ) in the Executive Office of the President (EOP) by Congress within the Act. CEQ issued regulations in 1978 to direct agencies on fundamental requirements for compliance with the Act.
Government employees understand that NEPA needs to be implemented within federal agencies to comply with the Act. However, levels of compliance with NEPA vary. Unlike most US environmental laws, there are no monetary fines associated with agencies' non-compliance with the Act (Knudsen, n.d.). As such, the public's oversight of federal actions, through public participation, Congressional complaints, and litigation, influence agency compliance with NEPA.
This study determines implementation methods employed by NEPA practitioners to integrate the Act and CEQ regulations into their agency, specifically within their decision-making and action planning processes. This study also identifies factors that impede integration of NEPA implementation methods into federal agency decision-making and action planning processes. Lastly, this study seeks to determine improvements in current implementation methods and processes that can be employed by federal agencies to better implement and comply with NEPA.
Twelve federal agencies were examined for this study, and 15 interviews were conducted with federal government employees working within the US Executive Branch. Eugene Bardach's (2012) policy research "tree of knowledge" was used to inform this study, with "people leading to people, people leading to documents, documents leading to documents, and documents leading to people." This study is based on Leo A. Goodman's qualitative research procedure in Snowball Sampling. The snowball sampling approach allows for this study to determine and understand methods implemented by federal agencies for NEPA compliance through interviews with a versatile group of NEPA practitioners.
This study identified four methods used by agencies to implement the NEPA process into federal decision-making. NEPA training allows decision-makers to initiate the NEPA process when an action is proposed. Programmatic environmental documents review any cumulative environmental impacts from geographical locations, projects, and cumulative actions. Master plans integrate NEPA into agency budget and project planning processes. Information Technology (IT) systems allow for institutional knowledge and historic NEPA reviews to be archived in IT Decision Support Systems (DSS) to create more effective NEPA reviews. IT Geographic Information Systems (GIS) are prevalent in federal agency decision-making to efficiently locate environmental attributes near potential action sites. Information- and knowledge-sharing, informed decisions, and archived NEPA documents are realized benefits of using IT systems for NEPA.
Practices implemented by agencies should make the NEPA process more efficient and effective to minimize federal actions' potential environmental impacts. As agencies introduce programmatic environmental assessments on a larger scale, data on environmental attributes in large geographical areas (e.g., centers, forests, installations) can improve GIS survey data. Federal agencies should move toward sharing environmental survey data so that current and relevant environmental attributes and constraints can be listed within one GIS platform. One centralized GIS platform would eliminate duplicative data collection efforts, thereby saving time and funding, and allow for valuable information-sharing.
NEPA guidance documents, regulations, memorandums, and data sets should also be located on a centralized website. This study recommends that CEQ transition to an EOP website to provide one centralized location for all NEPA guidance documents; a secure, comprehensive IT GIS platform; and a DSS for all EAs and EISs. A DSS should support EAs and EISs to be available for public information, with links to Regulations.gov for public comments to be submitted. NEPA documents not requiring public review and comment should be stored on individual agency DSS platforms.
Use of comprehensive IT systems for NEPA provides seamless environmental review processes and cohesive flow amongst agencies, between the federal government and the public, and over the years. With information electronically linked, decision-makers will be able to access a centralized CEQ GIS system to locate any environmental constraints near their proposed action site, thereby promoting efficient and effective environmental reviews. Agency DSSs should also be connected with the agency's allocation of funding so that NEPA is incorporated into decision-making processes before funding is provided.
Programmatic reviews can be conducted using centralized GIS data, both in individual agencies and collaboratively with other federal agencies. Further, electronic master plans can be more useful when linked to a centralized IT GIS and agency DSS platforms. Completed NEPA reviews can be readily available in DSSs for action proponents to integrate environmental considerations into their actions, for senior management to view project statuses, and for NEPA programs to access proposed, current, and historic reviews. Once IT systems are in use for agencies to comply with NEPA to the fullest extent possible, NEPA practitioners can identify and focus on other areas, including policies and implementing procedures, for NEPA compliance improvement.
Lastly, CEQ should update their 1978 NEPA regulations. The CEQ NEPA regulations influenced a transition from environmental impact statements (EIS) to categorical exclusions (CATEX), with 95% to 98% of actions currently qualifying for categorical exclusions. Because this shift was not foreseen, the NEPA regulations do not speak to the use of categorical exclusions at length. While guidance documents and memorandums have been published in the past 38 years, no revisions to the original mandate have been issued. NEPA program managers interviewed for this study believe CEQ should update the regulations to provide further clarification for problems still found in the NEPA process, including use of EAs and solutions for improved compliance.
Item Open Access North Carolina [Un]incorporated: Place, Race, and Local Environmental Inequity(2018) Purifoy, Danielle MarieCritical race scholarship of the past 20 years offers a robust foundation for interrogating connections between race, place, and environment, and their constitutive impacts on the lived experiences of people of color, particularly black and brown peoples. Less explored are the intersections of race and legal jurisdiction in the production of place inequities. Current scholarship from local government law, geography, environmental justice, and related disciplines suggests understanding the structure and process of municipalities may clarify how local jurisdiction shapes racial inequities in the built environment. This dissertation assesses the efficacy of the municipality as a political institution for equitable, community-sustaining, local development, particularly for black communities. Focused primarily in North Carolina, I assess three interrelated questions: First, I ask whether black and Latinx communities receive the same built environmental benefits from municipal incorporation as white communities. Second, I turn to two black towns in North Carolina to assess the extent to which black communities can rely on independent municipal incorporation to fulfill their aspirations for autonomy and resilient placemaking, focusing specifically on the development of the towns’ local water systems. Third, I consider the efficacy of black community-based institutions in North Carolina and Alabama to provide alternative forms of governance to address structural underdevelopment of black communities, perpetuated by often hostile, white-controlled governments.
Item Open Access PROSPECTS FOR REVENUE-SHARING IN REDUCING INEQUITIES IN DRINKING WATER INFRASTRUCTURE FINANCING(2023-04-28) Navarro, Addie; Retter, ClaireDrinking water infrastructure is aging across the United States and is in desperate need of significant capital investments. While federal funds designated for capital infrastructure improvements have increased in recent decades, the burden of financing these necessary developments falls overwhelmingly at the local level. Because drinking water is mainly paid for at the local level, this financial burden is passed to ratepayers. To build a conceptual foundation of the current state of this infrastructure, we conducted a broad review that aimed to understand four main themes: (a) the implications of widespread aging physical infrastructure, (b) the available pathways for financing capital investments at the local level, (c) chronic underinvestments in physical drinking water infrastructure, and (d) the inequities that both drive the issue and result from it. From our initial research, we identified the goals of shifting the burden of financing the necessary capital investments away from ratepayers and reducing utility dependence on the revenue generation capacity of the local service area. The guiding question of this project is how to finance critical improvements to drinking water infrastructure without exacerbating inequities at the local level. Because low-income communities are carrying the burden of repayment, our specific objective is to explore how equalization mechanisms could be applied at the state level to reduce the inequities between low-income and high-income communities at the local level. Our next step was to identify examples of successful equalization mechanisms at the state-level that we could draw lessons from. We turned our attention to public school financial reforms, which often focused on implementing equalization mechanisms to achieve either adequate or equitable funding in schools. Education finance reforms occurred through two primary eras; the first, less successful push for reform was based on arguments of equity, while the later, more successful cases were those rooted in concepts of adequate school funding. We then evaluated the main education funding formulas that resulted from these reforms. At the highest level, funding formulas break down into two categories: student-based and program and/or resource-based. From there, student-based structures break down into foundation grant or guaranteed tax base models, resulting in three main categories of funding formulas. Through five state-level case studies, we detailed the collection and redistribution processes for funding, the breakdown of state and local contributions, and isolated the equalization mechanism in each formula. Drawing from the equalization mechanisms identified in each school funding formula, we built a step-by-step parallel to how these formulas could be similarly applied to reduce inequities in drinking water payments. We identified the parallels in actors (e.g., students and households, school districts and utilities, etc.) and in measures (e.g., minimum cost to educate one student and the minimum cost to provide basic water service to one household), and built out theoretical models for how these formulas might look in the water sector. We conducted feasibility studies in two states, North Carolina and Washington, to characterize the existing landscape of potential legal, political, and fiscal barriers and/or opportunities to implementing policies of this type. The following report covers four main sections, (a) history and current challenges in providing drinking water, (b) education financial models and lessons learned, (c) applying these models to water, and (d) feasibility studies in Washington and North Carolina. Our conclusion distills the main takeaways from our research and highlights the success of education finance reform in improving equity in education funding across school districts. The main lessons learned from this project were that (a) adequacy-based language is more successful than equity-based language in passing financial reform legislation and achieving equalization outcomes; and (b) more research is needed to understand the feasibility of each of the three funding formulas in each state where it may be applied. To that end, we have provided a list of follow-up research questions to guide future inquiry into the success of implementing equalization mechanisms in the water sector to reduce drinking water inequities.Item Open Access Quantifying Racial Disparities in Water Affordability(2021-04-30) Sayed, Sara; Smith, HannahWater services are essential‚ for all populations, yet the affordability of water has emerged as a major challenge faced by community water systems. While water costs rise for an increasing number of public water utility customers, there is no mandate to ensure equitable affordability, only guidelines by the EPA. Under EPA guidance, the metric for water affordability was previously based on water costs as a percentage of median household income for the entire area served by a water system. Recently developed metrics quantify the water affordability burden with greater attention to lower income households. Specifically, the Household Burden Index‚ measures the cost of water services as a percentage of low-income households’ annual income. In addition to examining water affordability, it is also essential to assess the presence of inequalities between racial and ethnic groups. As such, this study examines racial and ethnic disparities in the affordability of water services in North Carolina. To determine the racial and ethnic composition of a water utility, this study implements a novel method of fitting block group level US Census data within water utility boundaries established with newly digitized service boundary maps. The study concludes there is a modest but significant correlation between low affordability of water services and higher proportion of black and Hispanic residents in a block group. Community water systems should apply our findings to affordability planning in their service areas.Item Open Access Small Drinking Water Systems in North Carolina(2019-04-26) Perry, Reed; Ramirez-Cisneros, Daniel; Xu, Yukun; Zhong, JizhenWe seek to improve understanding about small drinking water systems in North Carolina. By analyzing data on drinking water violations, individual system characteristics, and community demographics, and by speaking with system owners directly, we can enhance current knowledge about these systems and help to lay the groundwork for future research on capacity-building and system consolidation. Among small systems, mobile home parks and schools are two unique entities that help us narrow the scope of our research and explore often overlooked communities. Our research confirms and tests common assumptions about small drinking water systems: these systems do struggle to meet compliance and there are inherent disadvantages in resources. However, these systems are not necessarily bound for failure. We believe our research will help to illuminate solutions for challenges faced by small drinking water systems in North Carolina and across the United States.Item Open Access Standardizing Sustainability for Private Water Companies: Existing Standards and Future Opportunities(2017-04-28) Oh, Eunji; Waller, Vanessa; Zhou, MavisUnlike public utilities, private water companies are in the unique position of having access to financial resources beyond municipal funding, allowing them to pursue innovative solutions to complex water management problems. However, private water companies must work creatively within the confines of regulations as well as stakeholder and shareholder expectations. Private water companies, like all other businesses, are faced with the question of how much time and resources to put toward environmental concerns. In most businesses, this question is addressed by operationalizing the concept of “sustainability.” Many in the business community think of sustainability in terms of the “triple bottom line”— the synergy of environmental, social/societal, and financial obligations. This project takes an inside look at how private water companies—from the very large to the very small—utilize the concept of “sustainability” in their business operations. As we found after speaking with water utility managers from across the United States, sustainability is often perceived as such a sweeping, theoretical concept, that it can be difficult to figure out how to “use” sustainability in practice. However, we also found that many tangible opportunities exist to make utility operations more sustainable. In fact, most utilities are well aware of, and eager to embrace, the challenges presented by the goal of becoming a more sustainable company. In almost every business avenue, including financial management, operations, and even human resources, private water companies are searching for ways to improve their triple bottom line, even while confined by regulations and shareholder commitments. Sustainability standards—guidance documents designed to make sustainability practical for companies—have played a key role in allowing businesses to measure and market their progress. Some of these documents specifically address sustainability for water utilities. But are these standards actually doing their job? Or are they a deterrent, making sustainability seem impractical? Our task was to evaluate these questions and develop recommendations for an improved sustainability standard for private water companies. We accomplished this goal through phone interviews with utility managers and company executives, as well as literature review. We found that an improved standard must have four major components: 1) a clear definition of what “sustainability” means, in terms that are useful for water utility operations; 2) references to established business standards, thereby linking a water utility-specific standard to a broader business context; 3) a recognition that a variety of factors influence operations, and that utilities must tailor sustainability goals to local issues; and 4) an emphasis on applying technology to enable efficient benchmarking for sustainability goals. Standards are inherently limited in their ability to effect change, simply because each business has its own unique needs and challenges. However, improvement to existing standards is particularly timely, as technological innovation in the water industry, including smart metering and data analytics, is moving at a rapid pace. A water utility sustainability standard for the future has the potential to simplify and organize important goals in this evolving industry. It is primarily this ability—to simplify the lives of utility managers—that would make a new sustainability standard useful.Item Open Access Sustainability and Social Justice: Urban Urgencies in Compact Neighborhood Planning(2017-05-05) Rouse, ChandraSocial justice and sustainability are two concepts that have evolved in the past two decades to create challenging directions for the field of urban planning. While planners describe sustainability as including environmental, economic and social concerns in theory, numerous studies cite that social justice often gets undercut in practice and that sustainability is implemented to address environmental concerns. This research focuses on sustainability and social justice in order to understand how compact land use planning can advance both. The intent of this research is to explore the relationship between sustainability and social justice and how to advance social justice through compact land use planning. This thesis examines whether or not sustainability includes social justice and how sustainability interacts with social justice in addition to identifying obstacles to advancing social justice through compact land use planning. The recommendations presented will contribute to efforts to identify opportunities that planners can use to advance a sustainability strategy that is inclusive of social justice and complements social justice goals.Item Open Access The Politics of Local Service Provision in the United States(2021) Hansen, KathleenLocal governments in the United States spend more than $1.6 trillion annually on public service provision. Access to reliable public services is essential for health and wellbeing. But there are large disparities in access to services across the country. This dissertation asks why. Specifically, I examine the incentives and constraints that influence investment in services. Local governments fund service provision with revenue from local taxes, fees, and intergovernmental aid. The amount of revenue that local governments collect depends on the demographics of their jurisdiction. Demographics undergird the size of the revenue base, voter preferences over tax rates and fees, and the need and capacity to seek intergovernmental aid. Each standalone chapter of this dissertation examines one of these components. In the first chapter, I use data from the U.S. Census and Census of Governments to examine how income segregation between municipalities shapes local service expenditures in metropolitan areas. In the second chapter, my coauthors and I use data on water rates and local elections to test whether voters hold local elected officials responsible for increasing service fees. In the third chapter, I use data from service area shapefiles, the U.S. Census, and state agencies to assess whether resource-based differences in need and capacity correlate with the allocation of federal aid for water services. Understanding the politics of local service provision has important implications for equitable access to services.
